Answer:

$18 + 18\sqrt{3}$

Step-by-step explanation:

The rectangle has been split into two right triangles. The hypotenuse of the triangle (the diagonal) is 18. The angle in the triangle is 30. All right triangles have unique relationships between their sides depending on the angles. This triangle must be a 30 - 60 - 90 triangle and its sides will be a scaled version of $1 - \sqrt{3} -2$ .

The side 2 correspond to the hypotenuse of length 18. 2*9 = 18 and so the scale factor is 9. To find the remaining sides, multiply each side length by 9 from $1 - \sqrt{3} -2$ .

It becomes $9 - 9\sqrt{3}-18$ . So the rectangle is 9 by $9\sqrt{3}$ .

The perimeter of the rectangle is $9 + 9 + 9\sqrt{3} + 9\sqrt{3}=18 + 18\sqrt{3}$

The answer and steps to get the answer

Damm [24]

The two angles 2y and 4y-36 add up to 180 degrees since they form a straight angle (aka straight line). We'll use this to find y.

(2y) + (4y-36) = 180
2y + 4y-36 = 180
6y-36 = 180
6y-36+36 = 180+36
6y = 216
6y/6 = 216/6
y = 36

If y = 36, then 2y = 2*y = 2*36 = 72

The bottom right corner of the smaller triangle on the left has an angle of 72 degrees

Focus on this same triangle. It has angles 51 degrees (bottom left corner), 72 degrees (bottom right corner) and x degrees (top)

They add to 180 degrees
x+51+72 = 180
x+123 = 180
x+123-123 = 180-123
x = 57

-----------------------------------

In summary,

x = 57
y = 36

Answer: $17.78; 26.67; 35.56

Step-by-step explanation:

Given the following information.:

Price of cab = $2 per mile , irrespective of the number of passengers.

Alice's destination = 20 miles

Ben's destination = 30 miles

Calvin's destination = 40 miles

If the three share a cab, the cab fee will be (cost per mile * number of miles of the farthest destination).

($2 * 40) = $80

Let price = a, for 20 miles

Ben's mile = 30 miles = 1.5 times Alice's miles, then Ben's pay = (1.5a)

Calvin's mile = 40 miles = 2 times Alice's miles, then Calvin's pay = (2a)

Thus,

a + 1.5a + 2a = $80

4.5a = $80

a = $80 / 4. 5

a = $17.78

Ben's pay = 1.5a = $26.67

Calvin's pay = 2a = $35.56
